[Action]

In the present invention, the mobile device has only the wireless transmission function and the main body has only the wireless reception function, and the presence or absence of the incoming call is reported by the telephone bell as usual, but the incoming call is received at a place away from the telephone. When responding to a call, the mobile device (wireless transmitter) sends a radio signal to the main unit to inform the other party that he / she is at home, and to hold a line and make a proxy response until the call is answered. To do so.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a schematic block diagram of a telephone remote response device showing an embodiment of the present invention. In FIG. 1, 1 is a telephone line, 2 is a telephone, 3 is a main body of an incoming call answering device newly provided in this embodiment, and 4 is a wireless transmitter.

When the telephone 2 receives an incoming call, a bell rings to notify the incoming call. Since the user always holds the portable radio transmitter 4, he / she does not have to be in the vicinity of the telephone 2 and can be located at a considerably distant position. When the user hears the ringing of a bell in a distant place, the user operates the wireless transmitter 4 carried by him to transmit a wireless signal to the incoming call response device 3. The main body 3 receiving the wireless signal puts the line on hold and sends a message such as being at home to put the other party on standby. next,
The detailed configuration of the circuit and its operation will be described.

FIG. 2 is a circuit configuration diagram of the incoming call response device main body and the wireless transmitter in FIG.

In the incoming call answering device 3, 5 is an incoming call detection circuit, 6 is a power supply circuit, 7 is a wireless reception circuit, 8 is a signal identification circuit, 9 is a hold circuit, 10 is a message storage circuit, 11 is an external switch, 12
Is a hold release circuit. Also, in the wireless transmitter 4,
13 is a response button, 14 is a power supply circuit, 15 is a signal generation circuit, 16
Is a wireless transmission circuit.

When an incoming call is received on the telephone line 1, the incoming call detection circuit 5 detects 16 Hz of the incoming call signal, activates the power supply circuit 6, and starts supplying power to all circuits of the main body 3. On the other hand, when the user who hears the telephone ringing sound operates the response button 13 of the wireless transmitter 4 at hand, the battery-powered power supply circuit 14 operates, and at the same time, the signal generated by the signal generation circuit 15 has a specific encoded signal. And a weak radio wave is transmitted from the radio transmission circuit 16 in accordance with this encoded signal. The radio waves used do not require a license for a radio station specified by the Ordinance of the Ministry of Posts and Telecommunications. For example, weak radio waves in the 27 MHz band (electric field strength of 15 μV / m or less at a distance of 100 m) may be used.

In the wireless reception circuit 7 of the incoming call answering device main body 3, the wireless transmission circuit
When the radio wave from 16 is detected, this is detected by the signal identification circuit 8
After demodulating in, it is discriminated whether or not it is a target signal. When the signal is the target signal, the holding circuit 9 is operated to put the telephone line 1 in a DC loop state, and the message storage circuit 10 indicates to the line 1 that "I am at home and answer the call immediately." Message to that effect. Meanwhile, the user carrying the wireless transmitter 4 arrives at the telephone, picks up the handset of the telephone, and answers the wireless transmitter button 13
By turning off, the signals from the radio receiving circuit 7 and the signal identifying circuit 8 are cut off, and the line holding in the holding circuit 9 is released. Since the handset of the telephone is already off-hook, it is possible to talk with the other party without disconnecting the line.

When an incoming call arrives, the answer button 13 of the mobile device 4 is pressed at a place away from the telephone to put the line on hold, but another person happens to be near the telephone and can answer the telephone. Of course, sometimes the person can answer the phone. That is, in order to answer the call without turning off the answer button 13 of the mobile device 4,
An external switch 11 and a hold release circuit 12 for forcibly releasing the hold are provided. A nearby person, after pressing the external switch 11 on the telephone to release the hold, responds to the other party and if the call is to a user at a remote location,
The other party will be notified immediately and the user will be called.
